Solid and Hazardous waste is increasingly becoming a major environmental burden of most urban and industrial areas. An alarming rate of solid and hazardous waste arising in Asia and the world has been witnessed parallel to urbanization, industrialization and economic development. Issues such as the increase in volume, variety of soid wastes, their qualitative diversification, and the trans-boundary movement of hazardous materials and soaring prices of resources now bound. The Thematic Working Group on Solid and Hazardous Waste (Waste TWG) of the Regional Forum on Environment and Health in Southeast and East Asian Countries was established in 2007 to address many of these problems. The goal of Waste TWG is to ensure environmentally sound management of solid and hazardous waste, particularly municipal and medical waste, and promote the 3R's.
